Abstract
Description
Technical Field
[0001] This application relates to the field of tensioner housing technology, and more specifically to a tensioner device that is easy to assemble and disassemble. Background Technology
[0002] The tightening device mainly consists of a tightening strap, a fastener, and a metal end hook. These components work together to tighten and secure objects by hand or electric means. Currently, it is mainly used for tightening items on trucks, trailers, ships, or rails, as well as for binding and securing steel, timber, and various pipes. When the tightening device is not in use, a housing structure is required to store it and prevent the tightening strap from becoming messy or tangled.
[0003] However, most tensioner housings require cumbersome assembly when storing the tensioner, making subsequent disassembly and retrieval inconvenient. At the same time, they do not provide good restraint for the metal end hooks, causing the metal end hooks to collide and bend inside the tensioner housing during transportation and movement. Utility Model Content
[0004] Therefore, this application provides a convenient retractor device to solve the problems of inconvenience in disassembling and retrieving the existing retractor after storage, and the lack of effective limiting effect on the metal end hook.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A conveniently detachable tightening device includes a first housing, a limiting rod, and a fixing frame. A second housing is provided on the outer front end of the first housing, and a fixing post is fixedly installed on the outer rear edge of the second housing. The tightening body is placed on the upper inner side of the first housing.
[0007] A limiting rod is provided through the lower end of the first housing, and a spring located inside the first housing is connected to the outer end of the limiting rod.
[0008] The outer wall of the first housing is provided with a fixing frame, and a rotating shaft is provided through the connection between the fixing frame and the first housing. The rear end of the fixing column is provided with a prefabricated groove that is adapted to the fixing frame.
[0009] Furthermore, the rear end of the fixing post extends through to the outer rear end of the first housing, and the fixing post is connected to the first housing by a plug-in connection.
[0010] Furthermore, the fixing column and the fixing frame are arranged in a one-to-one correspondence, and the fixing frame is connected to the fixing column by a snap-fit method through a prefabricated groove.
[0011] Furthermore, the longitudinal section of the fixing frame is U-shaped, and the fixing frame forms a rotating structure with the first outer shell through a rotating shaft.
[0012] Furthermore, a fixing ring is integrally fixedly installed on the inner center of the first outer shell, and a positioning rod that matches and connects with the fixing ring is fixedly installed on the rear center of the second outer shell, with a positioning protrusion for positioning provided on the outer side of the positioning rod.
[0013] Furthermore, a metal end hook is provided at the lower end of the tightening device body, and the metal end hook is connected to the limiting rod.
[0014] Furthermore, the limiting rod is slidably connected to the first housing, and the lower end of the limiting rod extends to the outer side of the lower end of the first housing.
[0015] Compared with the prior art, this application has at least the following beneficial effects:
[0016] 1. The fixing frame forms a rotating structure with the first outer shell through a rotating shaft. When disassembling, the fixing frame is rotated upward to separate the fixing frame from the precast groove, thereby losing its fixing effect on the fixing column and the second outer shell, and the second outer shell can be disassembled, which improves the convenience of disassembly and assembly.
[0017] 2. The metal end hook at the lower end of the tightener body is hooked to the middle of the upper end of the limit rod, causing the limit rod to move upward and stretching the spring. At this time, the spring exerts a downward force on the limit rod, thereby improving the tightness of the connection between the limit rod and the metal end hook, and thus limiting the metal end hook to prevent it from shaking inside the first shell.
[0018] 3. The fixing frame can move into the precast groove through the middle and engage with the fixing column through the precast groove, which facilitates the fixing of the fixing column and thus fixes the second shell, making the fixing of the second shell more convenient.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1 to 3 As shown, a conveniently detachable tensioner device according to the first aspect embodiment of this application includes a first housing 1, a limiting rod 6, and a fixing frame 9. A second housing 2 is provided on the outer front end of the first housing 1, and a fixing post 3 is fixedly installed on the outer rear edge of the second housing 2. A tensioner body 8 is placed on the upper inner side of the first housing 1. The interior of the first housing 1 is provided with a cavity structure to facilitate the placement of the rolled tensioner into the interior of the first housing 1. A fixing ring 4 is integrally fixedly installed in the middle of the inner side of the first housing 1. The fixing ring 4 can position the tensioner to maintain the winding state of the tensioner.
[0027] A limiting rod 6 is installed through the lower end of the first outer shell 1, and a spring 7 located inside the first outer shell 1 is connected to the outer side of the limiting rod 6. A metal end hook is provided at the lower end of the tightening body 8, and the metal end hook is connected to the limiting rod 6. The limiting rod 6 is connected to the first outer shell 1 in a sliding manner, and the lower end of the limiting rod 6 extends to the outer side of the lower end of the first outer shell 1. After the tightening body 8 is stored, the metal end hook at the lower end of the tightening body 8 is hooked to the middle of the upper end of the limiting rod 6. At this time, the force generated by the tightening body 8 on the limiting rod 6 causes the limiting rod 6 to move upward and stretch the spring 7. At this time, the spring 7 generates a downward force on the limiting rod 6, thereby improving the tightness of the connection between the limiting rod 6 and the metal end hook, and thus limiting the metal end hook to prevent it from shaking inside the first outer shell 1.
[0028] The rear end of the fixing post 3 extends through to the outer rear end of the first outer shell 1, and the fixing post 3 is connected to the first outer shell 1 by a plug-in connection. A positioning rod 5 that matches and connects with the fixing ring 4 is fixedly installed in the middle of the rear side of the second outer shell 2. The outer side of the positioning rod 5 is provided with a protrusion for positioning. After being stored, the fixing post 3 is inserted into the inner wall of the first outer shell 1. At this time, the positioning rod 5 is inserted into the inner wall of the fixing ring 4, which facilitates dual positioning through the fixing post 3 and the positioning rod 5, so as to improve the accuracy of the installation of the second outer shell 2.
[0029] A fixing frame 9 is provided inside the outer wall of the first outer shell 1, and a rotating shaft 10 is provided through the connection between the fixing frame 9 and the first outer shell 1. A prefabricated groove 11 adapted to the fixing frame 9 is opened inside the rear end of the fixing column 3. The fixing column 3 and the fixing frame 9 are arranged in a one-to-one correspondence, and the fixing frame 9 is connected to the fixing column 3 by a snap-fit method through the prefabricated groove 11. The longitudinal section of the fixing frame 9 is "U" shaped, and the fixing frame 9 forms a rotating structure with the first outer shell 1 through the rotating shaft 10. As the fixing column 3 is fully inserted into the interior of the first outer shell 1, the rear end of the fixing column 3 protrudes from the rear end of the first outer shell 1. At this time, the fixing frame 9 is rotated backward, so that the fixing frame 9 rotates inside the first outer shell 1 through the rotating shaft 10, so that the middle part of the fixing frame 9 can move into the prefabricated groove 11 and engage with the fixing column 3 through the prefabricated groove 11, thereby facilitating the fixation of the fixing column 3 and thus fixing the second outer shell 2, making the fixation of the second outer shell 2 more convenient.
[0030] When it is necessary to disassemble the second outer shell 2 and remove the tightening device body 8, the above steps are reversed to separate the fixing frame 9 from the prefabricated groove 11, thereby losing the fixing effect on the fixing column 3 and the second outer shell 2, improving the convenience of disassembly and assembly.
[0031] The technical features of the above embodiments can be combined in any way as long as there is no contradiction in the combination of these technical features. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
